The Rocky Horror Picture Show movie debuted on theater screens in 1975 and by 1976 it had earned its midnight movie status. Part of its midnight movie status was the growing trend of audience participation during the movie. That eventually became known as shadowcast in which live actors act out and lip sync the movie during the movie screening. This would include audience participation such as, call back lines to the screen and certain props being used during the movie as well as other audience participation.
